## Description

- description: The possibility of almost linear tuning of the band gap and of the
    electrical and optical properties in monolayers (MLs) of semiconducting transition
    metal dichalcogenide (S-TMD) alloys opens up the way to fabricate materials with
    on-demand properties. We investigate the optical properties of WSSe MLs with an
    S/Se ratio of 57/43 deposited on SiO2/Si substrate and encapsulated in hexagonal
    BN (hBN) flakes using photoluminescence (PL) spectroscopy. Similarly to the ”parents”
    WS2 and WSe2 MLs, we assign the WSSe MLs to the ML family with the dark ground
    exciton state. We find that, except for the neutral bright A exciton line, three
    observed emission lines are associated with negatively charged excitons. The application
    of in-plane and out-of-plane magnetic fields allows us to assign undeniably the
    bright and dark (spin- and momentum-forbidden) negative trions as well as the
    phonon replica of the dark spin-forbidden complex. Furthermore, the existence
    of the single photon emitters in the WSSe ML is also demonstrated thus prompting
    the opportunity to enlarge the wavelength range for potential future quantum applications
    of S-TMDs.
